BOTTLE-STOPPERING DEVICE.

SPEGIFIGATIQN forming part of Letters Patent No. 7 13,638, datedNovember 10, 1903.

Application filed March 2, 1903.

To to whom it may concern.-

Be it known that I, WILLARD R. GREEN, a citizen of the United States,residing at Donver, in the county of Arapahoe and State of Colorado,have invented certain new and use-: ful Improvements inBottle-Stoppering Devices, of which the following isa specification. Oneof the objects of this invention is to ively placing and retaining inposition a valve or seal within the neck of a bottle or other vessel,and which means may be placed or contained entirely within the neck ofsaid bottle, whereby it is not subject to disturbance from outside oraccidental influence.

Embodiments of the invention are illustrated in the drawingsaccompanying this specification, of which- Figure 1 represents anelevation, partly in section, showing the seal and the attachedmechanism in place in the neck of a bottle. Fig. 2 represents a modifiedform of the same with a different means for crowding or compressing theparts. Figs. 3 and 4 represent other forms of the diiferent parts. Fig.5 is a plan view of the retaining devices employed in Fig. 3. Fig. 6shows a modified form of the arms wherein a reversed curve is providedin order to give additional elasticity to the arms. Fig. 7 shows afurther modification in which the arms and levers are formed from onestrip of metal. ther modification.

In the drawings, A represents a bottle having aseat 13 within the neckthereof and having bearing-surfaces O, which may be projections upon ordepressions in the material of the vessels neck at or near the top orouter extremity thereof.

D is a seal of the valve type, containing on its lower side or seat alayer of cork or other suitable material and adapted to take a seat uponand form a seal with the seat B in the neck of the vessel. Operativelyconnected with the said disk or seal are curved arms E, preferably madeof spring metal. The said arms E are adapted to engage with their outerends the bearing-surfaces O, and when in such position the seal D is inoperative contact with the seat B, but not under pressure from the saidarms. Operatively connected with the arms E are the levers G,

Fig.8 shows a fur- Serial No. 145,780. (No modem also ,operativelyconnected with the lever H upon the handle or lever I.

It is obvious that upon moving the levers G through the handle I thesaid levers will act upon the backs of the curved arms E and tend tostraighten them or depress the said curve, whereby the said arms areelongated in line with the dotted lines K and the force thereof isapplied upon the valve or disk to powerfully seat the same upon the seatB. It will be seen that the leverage thus applied to the arms B is atsuch an advantage as to produce practically a maximum pressure upon theseal and'which may be so adjusted and proportioned as to producepractically any pressure desired. Itis also obvious that the levers Gand H may be so proportioned as to give a naximnm advantage in leverage,and thus the handle I may be very easily moved while producing a verygreat force upon the seal, and that the parts of said levers may be soconstructed as to pass the dead-center and to lock themselves intopositiou. It is also evident that the handle I may be formed anddisposed to lie entirely within the neck of the vessel and to be freefrom outside interference, while at the same time be freely accessibleto the fingers, which will be amply sufficient to either seat or removethe seal.

In the modified forms shownin Figs. 2 and 3 it will be seen that thesaid levers may be similarly altered and disposed, so as to givecorresponding advantages with those stated respecting Fig. l.

In Fig. 4 the action and efiect of the re versed curve L M will bereadily seen, and the principle is that a yielding will be obtained inthe arms E by a bending at the cross-sections L and M before thelongitudinal thrust is fully applied from the straightening of the upperportion of said arms, and

' or bring them into a straight line,or approximately so, whereby thesame elongation of the said arms is obtained and the resulting force isapplied to the said seal.

Any form of suitable wrench may be employed for this purpose, and theform shown in Fig. 6 is suitable, or a lever Gr may be directly thrustthrough or applied upon the said arms, as shown in Fig. 8, made ofstamped sheet metal and provided with two lugsg to bear against thecurves. Only one lug g is seen on each lever G in Fig. 8.

In Fig. 7 the arms E and levers G are made from a single strip of metal.

It is obvious that the form and application of the invention may bevaried and modified without departing from the principles of theinvention; also, that the parts of the vessel may be likewise varied andthat the seat or mouth of the bottle-neck may be given any angle ortaper and that a seal or stopper of any ordinary form may be used; also,that by adapting the arms any length of throw or travel of the seallongitudinally in the neck may be obtained and a powerful wedging orseating of a stopper produced. The parts may be used to release andwithdraw the seal or stopper.

What I claim is- 1. In a bottle-seal the combination with a bottlehaving a seat within the neck thereof and having bearing-surfaces abovesaid seat within said neck at or near the mouth of said neck, of a sealor stopper adapted to make a sealing contact with said seat, armsconnected to and extending upward from said seal in other than a directline and adapted to take a bearing upon said bearing-surfaces, withmeans for straightening the said arms whereby they are elongated upon adirect line and a pressure is produced upon said seal.

2. In a bottle-seal the combination with a bottle having a seat withinthe neck thereof and having bearing-surfaces at or near the upperextremity of said neck, of a seal adapted to making a sealing contactwith said seat, curved arms connected with and extending upward fromsaid seal, adapted to make an operative contact with saidbearing-surfaces, and means for compressing or straightening said curvedarms more or less to a'straight line, whereby a pressure is applied tosaid seal to seat the same.

3. In a bottle-seal, the combination with a bottle having a seat withinthe neck thereof and bearing-surfaces at or near the upper extremity ofsaid neck, of a seal adapted to make sealing contact with said seat,curved arms connected therewith extending upward to make an operativecontact with the bearing-surfaces and bent upon themselves to formlevers operatively connected and coacting to depress or straighten thesaid curved arms to apply pressure upon said seal, substantially as setforth.

In testimony whereof I have signed my name to this specification.
